You can see your sales history here: http://500px.com/settings/store/sales (View Transaction History). We're working on some contributor newsletters which should have some interesting data.  If you have a lot to submit, Alex (@500alexs) has mentioned that you can contact us at [email protected] and we may be able to help with large collections such as yours.

Once you submit your content for licensing it's immediately searchable on 500px Prime, and if I a buyer requests to license it before our reviewers have reviewed the file (usually just under 2 weeks now) we'll by-pass the queue and vet the file immediately. 500px Prime (http://prime.500px.com) is much more focused as a commercial licensing marketplace without the community elements of 500px.com that you mentioned.

Not sure why that direct share link doesn't work you.

I don't check these forums very often, but I did want to say that it wasn't arrogance that prevented us from replying to everyone.  It was a technical failure on our part.  It's something we've apologized for in the past (in Facebook, over emails, etc.). We didn't have a mechanism to reply to the amount of portfolios we initially received. We've corrected that and now send emails after a Call to Artist submission or Application is reviewed.  It was a stupid mistake on our part and was not intentional.  We fixed it as soon as we could.
